Details:
The fix for https://savannah.gnu.org/bugs/?22010 is incomplete. When make
restarts itself due to an updated makefile it re-exec's itself inheriting the
increased stack rlimit but without remembering the original saved values so
the re-exec'd make will run its subprocesses with the increased stack limit.
This sequence of commands demonstrates the bug:
$ ulimit -H -s
32768
$ ulimit -s
4096
$ cat Makefile
include foo.inc
foo.inc: bar.txt
touch $@
show-stack-rlimit:
ulimit -s
$ echo > foo.inc
$ echo > bar.txt
$ make show-stack-rlimit
touch foo.inc
ulimit -s
32768 <-- inherited the stack increase to the hard limit
$ make show-stack-rlimit
ulimit -s
4096
The attached patch resolves the issue for me.
